" TaZZ whom it may concern v ,axle 1 from the 'wheels of the vehicle will Be it known that I, Groen M. HUs'roN, a -cause `a relative movement of the outer ends citizen of the United States, residing at New of leaf spring downwardly with respect to York, thel borough of 'Manhattan and said axle, and a corresponding downward 60 5 State of [New York, have'inyented new and movement of the outer lends of shackles-8 on useful Improvements in Vehicle-Springs, of their pivots 10, thecurvcd configuration at 6 which 'the following is aspecitication. of said leaf springs freely permitting this My invention relates to vehicle springs, movement.' In consequence the lower ends i and vis ,more particularly intended' for use of springs 11 are carried downward in vary- 65 10j with motor vehicles, and has for its object to ing4r degree according to the distances of provide `certa-in improvements in -the contheir Apoints y of attachment to shackles 8- stru'ction and arrangement of the Same, as from the pivotslO, the lighter inner leafbewill be hereinafter moreparticularly point- 'ing carried farther -than the outer heavier ed'out and claimed, retereneebeingl had to leaves. This 'results in `a` progressively in- 70 .15 the accompanying drawing, in which:- creased area of contact between the faces of Figure 1 `is a side elevation of my 'iinsaid springs fromK their common point ofv .roved construction shown applied to a veconnection 13 with the vehicle body toward hicle axle and body, said axle beingshown their separated points of connection with the i inl section. Fig. 2 is a similar view on a shackles 8,. which will vary in accordance 75 smallen'fs'cale illustrating a modied conwith the shock imparted to axle l, and as 'struction'. v said area of contact increases, the rigidity of In the said drawing the reference numeral said leaves increases correspondingly to af 1 denotes one of the axles-of an automobile' ford a progressive increase in the resist-ance or other vehicle,v the same being shown" I-` offered to the shock, until the latterv is coin- 80 shaped in cross section, though it may be of pletely absorbed. f any configuration. Bolted to said axle at 2 It will be seen from the drawing that beisf-a plate 3, t-h'e'same havin formed integral ginning at` substantially the points where A therewith `an arm/JiA depen ing at each side the clips 14C are located the leaves 11 are of said axle, as shown. llBoltedor otherwise formed on the arcs of true circles of varying 85 tlxer to said' plate 3 is a leaf spring 5, diameters1 'which construction permits of formed of any desired number ofleaves, and their accurately registering in progressive projecting equidistant,"transversely to each contact with each other while absorbing side of the axle 1, said spring being moved shocks imparted to the axle 1. To accommodownwardly and inwardly at ,its yoiiter ends date lighter loads, -I shift the point of con- 90 6, vfor `a purpose hereinafterto be described. nection of eachvleaf 11 outward one or more Pivotallyconnected at A7, to-each free end of of the holes 9- in' shackles S, which adjustlsaid spring 5 is la rigid bar or shackle 8 prefnient throws more 'pressure on the` leaf erably slightly curved downwardly at its springs 5 and causes the vehicle body t0 ride outer end :and provided along its length easier. In order to maintain the relative pov95 40 with a plurality of bolt receiving apertures sition of the leaves 11, I pre-ferably'arrange 9,said bar being shown pivotally connected on them suitable clipslll, as shown. 'at its inner 'end at l0 with the lower end of It will be understood that while I have one ofthe arms 4 of plate 3. Pivotally conshown the leaves 11 extended to opposite nectd tosaid shackle 8, through the bolt sides of the axle l, my improved .construc- 100 holes or apertures 9 are the ends o f a series Ation is .equally as effectiye and will operate `of springleaves 11, the same sweeping therein the same manner when said leaves are disfroin upwardly' in the arcs of circles and be posed on one side only of said axle and ing conjointly connected to the body12 of terminate;` at the point 13 .on the vehicle the vehicle at a vpoint 13 directly above the body, the shackle 8 and that portion of leaf 105 axle l, said leaves extending in similar conspring 5 upon the opposite Vside of axle 1 figuration downwardly again to the shackle being of course also dispensedwith. While 8 on the opposite side of axle 1. I 'preferito I have shown three leaves 11 it will be ungraduate the thickness ot said leaves 1.1, the derstood that I may .employ two, four or. l outermostv being lthickest and the innermost more, in accordancewith the load to be sup- 110 the thinnest ported.

In operation any shock imparted to the In Fig'Q I-havefillustrated a modified.

construction 1n wnicn my improved device is applied in connection with a semi-elliptic spring pivo-ted to the vehicle body at 16 which is as to its upper leaves extended into va spring similar to one end of spring 5 of Fig. l, the leav-es 11 and shackle-8 being identical in construction and operation with that of one half of the Fig. l` construction. This embodiment I employ on the front axles of automobiles and other vehicles to better take up the longitudinal strains.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is l. A spring construction for vehicles, embodying a plurality of similarly l curved spring leaves fixed to one member in contact with each other and gradually separating toward their points of connection with the other member, a shackle pivoted at one end to said other.member and to which the separated ends of said leaves are connected intermediate its length, and a spring also xedto said other member and resiliently .supporting the free end of said shackle.

'2. In a spring construction for vehicles, a body to be supported, a plurality of similarlycurved spring leaves fixed thereto in contact with each other, and gradually separating as they lleave said body, a running gear, a shackle pivoted at one'end'to said running gear -and to which said leaves are separately pivoted at their separated eds,

and a spring also mounted on said running c gear and resiliently supporting the free end of said shackle to permit movement thereof on its pivot under relative movement of the parts, whereby said body spring' leaves will be shifted by the movement of .said I the arcs of true circles from their point of contact Witheach other to their separated ends.

4. A spring construction :for vehicles, em, bodying a plurality of nested spring leavesl curved on the arcs .of true circles but of different diameters and disposed in contact with each other at one end and fixed to one member of the vehicle and gradually separating toward their'other ends, a shackle pivoted at one end to the other member and to which the separated ends of said leaves are connected Vintermediate its' length, and a spring also Xc-d to said other member and resiliently supporting the free end of said shackle.
